A compressor ratio is one of the most misunderstood parameters in music production. But when you understand what its purpose is and how to use it properly, your sounds and mixdowns will rise in quality very quickly.<\/h2>\n\n\n\n

Many beginners don’t understand what an audio compressor ratio is actually doing to their sound. Well, it’s time to change that.<\/p>\n\n\n\n

Audio Compressor Ratio Explained <\/h3>\n\n\n\n

Put simply, a compression ratio is what sets the amount of gain reduction (or amplification in upwards compression) your compressor<\/a><\/strong><\/span> will apply to your signal. Additionally, a compressor expresses ratio levels in decibels (dB). However, your audio compressor will not kick in whatsoever until your signal breaches the threshold that you have set.<\/p>\n\n\n\n

\"Compression<\/figure><\/div>\n\n\n\n

Let’s talk about an example. With a ratio of 2:1, your compressor will attenuate your signal by 1dB for every 2dB that your signal breaches the threshold. If you have a ratio of 4:1, your signal will be attenuated by 1dB for every 4dB that your signal breaches. <\/p>\n\n\n\n

But at the extreme end of compressor ratios, we have limiters. A limiter essentially sets a dB ceiling that your signal cannot breach whatsoever. This is why it’s called limiting! Furthermore, the ratio for limiting is 10:1 (or higher) or inf:1, as we have presented in the above image. <\/p>\n\n\n\n

And if your ratio is 1:1 then no compression will occur whatsoever. <\/p>\n\n\n\n

You should be starting to see that the ratio parameter on your compressor is where a lot of your attention should be at. Too high a ratio will flatten your sound, and too low a ratio won’t do the whole job.<\/p>\n\n\n\n

With all of this in mind, now you can better grasp that your ratio knob is what determines the amount of compression that the compressor will apply. The numbers themselves are indicators that relate to the ratio of input to output. <\/p>\n\n\n\n

If you use a higher ratio then you’ll get more compression.<\/p>\n\n\n\n

The ratios available on any given compressor do depend on the type and manufacturer of the compressor. Below is a list of common ratio settings available on pretty much every compressor.<\/p>\n\n\n\n
